Answer:
D
Explanation:
Two plane mirrors are inclined at 70∘. A ray incident on one mirror at incidence angle θ after reflection falls on the second mirror and is reflected from there parallel to the first mirror, The value of θ is. ∴(θ)=50∘.

Answer:
The acceleration
Explanation:
The slope of velocity time graph is the acceleration
Answer:
KE (5) = 1/2 M V^2 = 25/2 M
KE (10) = 1/2 M V^2 = 100/2 M
KE (10) - KE (5) = M/2 (100 - 25) = 75/2 / M
An object traveling at 10 m/s has 4 times the kinetic energy as an object traveling at 5 m/s
Total work would depend on the mass being accelerated
